WIND MOTOR.

Application filed March 22, 1926.

es to wind-propelled This invention remotors or windmills.

The primary object of the present invention is to provide a motor of this character will utilize the power of the wind to :it than hitherto. Another oba l ect is to provide a motor construction in the windsails arranged to re- P t a vertical and are interconirrigation and other purposes requiring relatively large amounts of power.

More specific objects will appear in the following description.

e invention consists in the novel con- 1 tion, adaptation and combination of hereinafter described and claimed.

- the accompanying drawings,

"ll'i, 1 is a view in vertical section of a l)lu on of a wind-motor illustrating an embodiment of the present invention. F ig. 2 is a plan view, soi'newhat diagrannnatic, of the motor illustrating the arrangement sails and the controlling connections 3 is a perspective view illusiatine the preferred manner of securing a ms rigidly to the mast. Fig. 4 s a perspective view of a portion oi the 111:.st and devices associated with the sailconlrollinp; appliances. Fig. 5 is a fragmentary perspective view of one of the sail members.

l n said drawing, the reference numeral repi vnts a rotary vertical shaft or mast whose lower end is jonrnaled in a foot hearing provided within a casing 11 wlieh is desirably supported by means of gimbal devices 12, or an equivalent, above a foundation 13.

The upper end of the mast is journaled in a ring 14 which, in the illustrated embodiment, connected as by means of guys 15 with suitable anchor posts or an equivalent, not shown, to maintain the mast sub ally vertical. rtiizidlv secured to the mast, as by means or". chcel; block. 16 are pairs of radiat arms 7 and 18, tour pairs being shown. The complementary arms 17 and 18 or each pair thereof are arranged paral- Serial No. 96,451.

lel, or nearly so, with each other and in the same vertical plane.

Stay members 19 and 20 extend from the mast above and below each pair of arms to the outer ends of the latter, such ends also beiny' connected with each other by a stay comprising a central vertical member 21 having its ends connected to the ends of the adjacent mast-arms through the medium of swivel devices which are indicated by 22 in Fig. 1.

The association, above described, of the st and the mast-arms constitute a truss with respect to the mast and also serve to retain the ends of complementary arms 17, 18 in vertically spaced apart relations. The ends 01 the upper and lower tiers of arms 17 and 18, respectively, are connected with each other circumterentially of the motor by braces 23 as shown with respect to the upper arms 17 in Fig. 2.

Secured intermediate their lengths to each of the stay members 21 are vertically spaced apart booms having arms 2 1 and at one site of the respective stay member 21 and arms 24 and 25 at the opposite side thereof.

The boom-arms 24 and 25 are connected with each other by crossed stays 26, each formed of complementary members which are adjustably coupled as by means of a turn-buckle 27.

The purpose of the stays 26 is to maintain the companion booms substantially horizontal and in parallelism with each other.

The arms 24 and 25 of each pair of companion booms are, in proximity of their free ends, connected by a stay, such as indicated by 28 in Fig. 1, which is parallel with the stay member 21 to which the respective booms are secured.

Located between the arms 24 and 25 is a sail 29, preferably of canvas or other suitable flexible material; the lower edge 01" a sail being secured, as by lacings 30, to the boom arm 25 the upper edge of the sail being secured, as by lacings 31, to a horizontally disposed pole member 32.

Between this member and the lower edge of the sail the latter is connected to one or more intermediate members, or cleats 38 two being shown in Fig. 1. Said cleats are connected in horizontal positions to the sail as by lacings or, preferably, by means of strips 34: 0t flexible material which are sewed to the sail.
